Hormone replacement therapy is an older way of describing what is now called hormone therapy. There is no difference as such.
In hormone therapy, an external hormone is given to the person for either what their body organs are not producing at all or which is being produced in a reduced amount compared to what is required by the body for proper functioning.
Hormone therapy is used to treat many disorders. Patients with hypothyroidism can be given synthetic thyroid hormone to restore the metabolic rate of the body. Hormones are used to treat mental disorder like depression and suicidal tendencies. Women are given hormones to deal with problems related to menopause.
These are just a few examples of the applications of hormone therapy. Many more are being discovered with the accelerated pace of research here.
It is completely different from hormone replacement therapy as it works against hormone-receptor-positive breast cancer. HRT is a medication prescribed to battle symptoms of menopause. It is not a breast cancer treatment and it is considered relatively unsafe, particularly for women already diagnosed with breast cancer.
Hormone therapy medicines are used to treat hormone-receptor-positive breast cancers. This type of medication works in two ways: it lowers the amount of the hormone estrogen in your body and it blocks the action of estrogen on breast cancer cells.
The larger quantity of estrogen in your body is produced in your ovaries. Your estrogen hormones naturally react to hormone-receptor-positive breast cancers by making them grow. Theoretically, by reducing the amount of estrogen or blocking its action through hormone replacement can reduce the risk of early-stages of hormone-receptor-positive breast cancers. If you are a patient who has had a history of breast cancer and has already undergone surgery, hormone therapy reduces your risk of the cancer from recurring. Hormone therapy medicines are also be used to shrink or slow the growth of “advanced-stage” or metastatic hormone-receptor-positive breast cancers. They are not, however, effective in busting hormone-receptor-negative breast cancers.
Hormone replacement therapy, on the other hand, is a prescription medication that is used to increase your estrogen levels. It was originally designed for women who were believed to be estrogen deficient due to menopause.
